Philips 74HC240 Octal buffer/line driver; 3-state; inverting DIP20

Manufactured by Philips - DIP20 Package

The 74HC240 is a high-speed Si-gate CMOS device and is pin compatible with Low-Power Schottky TTL (LSTTL).

The 74HC240 is a dual octal inverting buffer/line driver with 3-state outputs. The 3-state outputs are controlled by the output enable inputs 1OE and 2OE. A HIGH on nOE causes the outputs to assume a high impedance OFF-state.

The 74HC240 is similar to the 74HC244 but has inverting outputs.
